Description

Technical Field

[0001] The utility model belongs to the technical field of mining engineering equipment, in particular to a shaft and lane sealing device. Background Art

[0002] During underground mining, it is necessary to dig a number of criss-cross tunnels underground. As the mining work progresses, some tunnels will be idle for a period of time due to poor ore, while the workers frequently move in the tunnels with a large amount of minerals. However, the ventilation conditions in the underground tunnels are limited. In order to improve the utilization efficiency of underground air, it is necessary to guide the airflow into those tunnels with a large amount of minerals to meet the survival needs of the workers and avoid the airflow from entering those idle tunnels. In addition, there is a large amount of toxic waste gas in the mine. The workers also need to guide the waste gas to be discharged out of the tunnel in time to avoid the waste gas from entering the working tunnels where people are active frequently. Therefore, the workers usually need to select certain tunnels for closure to adjust the airflow path.

[0003] In the prior art, the patent document with the publication number of "CN203685291U" discloses a rapid tunnel sealing system, which is composed of a tunnel fire wall, a tunnel connection control device, an air-tight bag and an inflation device. The tunnel fire wall is arranged on both sides of the tunnel entrance; the tunnel connection control device is composed of a connecting ring and a rope net, the connecting ring is fixed on the tunnel ceiling, and the rope net is suspended on the tunnel ceiling through the connecting ring; the bottom of the air-tight bag is provided with an inflation port, the inflation port is connected to the inflation device, and the air-tight bag is placed in the rope net. By adopting the patented technical solution, the air-tight bag is matched with the rope net, so that the whole device can be quickly fixed in the tunnel, and the corresponding tunnel can be quickly sealed, and the airflow path can be blocked or changed. However, when installing the rapid tunnel sealing system, the air-tight bag needs to be inflated. Since there is no corresponding guide structure, the air-tight bag will expand in any direction, resulting in that the local area of ​​the air-tight bag cannot completely fit the tunnel wall, affecting the tunnel sealing effect.

[0004] In order to solve the above technical problems, the utility model provides a shaft and lane sealing device.

[0005] The utility model is realized through the following technical solutions.

[0006] The utility model provides a shaft and tunnel sealing device, comprising a surrounding frame, an air bag, a pair of sealing plates and a plurality of telescopic rods, wherein the sealing plates are fixedly connected to the left and right sides of the surrounding frame, the air bag is wrapped around the surrounding frame and clamped between the pair of sealing plates, and the telescopic rods are hinged at the edges of the sealing plates.

[0007] The shaft and tunnel sealing device also includes a plurality of expansion bolts. The telescopic rod is also fixedly connected to the first hook. One end of the expansion bolt is buried in the tunnel surrounding rock, and the other end of the expansion bolt is fixedly connected to the second hook.

[0008] The number of the expansion bolts is equal to the number of the telescopic rods.

[0009] The number of the telescopic rods or expansion bolts is no less than 16.

[0010] The telescopic rod can be replaced by a pneumatic spring rod.

[0011] The surrounding frame comprises a pair of positioning rings and a plurality of supporting tubes. The pair of positioning rings are opposite to each other, and the supporting tubes are fixedly connected between the pair of positioning rings.

[0013] The positioning ring is in a circular ring shape or a rectangular shape.

[0014] The supporting tube is a rectangular steel tube or a circular steel tube.

[0015] The sealing plate is a circular thin plate or a rectangular thin plate.

[0016] The beneficial effect of the utility model is that: by adopting the technical solution of the utility model, the frame is moved to the tunnel that needs to be closed, and then the airbag is inflated, and the airbag expands and fits the inner wall surface of the tunnel, thereby realizing rapid sealing of the tunnel, blocking or changing the airflow path. Since the airbag is clamped between two sealing plates and between multiple pairs of telescopic rods, when the airbag is inflated, the airbag can only expand along the surface of the sealing plate and the axial direction of the telescopic rod. The sealing plate and the telescopic rod have a guiding effect on the expansion direction of the airbag, so that the airbag can completely fit the inner wall of the tunnel, thereby improving the sealing effect of the tunnel.
